Here is a longer video showing multiplication, algebra and division. The lesson is simplified by keeping in mind the five basic concepts, and having blocks the child can get her hands on. In my travels I found that the saying math is not a spectator sport was QUITE TRUE. Just watching is not enough, you need to get your hands on the blocks. It was became apparent the difference between everybody in the room "getting it" and "only" getting 80 or 90% of the room was to make sure everybody had a set of blocks or were sharing a set of blocks, but everybody had to be able to have their hands on the blocks.
If you don't "get it" you may be one of those people that needs to get your hands on the blocks.
This child is supposed to be special ed or SPED, I doubt many of her SPED-mates are doing math like this. Children doing math like this at 6 or 7 years of age would be considered gifted...but actually when they can see what they are doing ANY little kid (or big kid as the case may be) can do math. I often say if you can speak English, count to 9, identify a rectangle and tell whether things are same or different, you can do math...
